Application filed June 23, 1915. `Serial No. 35,912. l

Philadelphia7 in the county oir Philadelphia i and State of Pennsylvania, have invented certain new and useful Improvements in Combination Gras-Ranges and -Water-Heaters, of which the following is a specification.

My invention relates to gas ranges.

The obj ect of my invention is to construct such ranges with water heating means for a continuous supply of hot water and also means for storing a quantity of water for bathing and washing, besides a receptacle for supplying small quantities of hotwater supply of gas to the burners, so that a flame will always be present for the ignition of the used for kitchen purposes. I

ln the drawing Figure 1 is afront view and Fig. 2 is an end view of Fig, 1. Fig. 3 is a plan view and Fig. i is a cross section ci cooking top 2.

Similar letters refer to similar parts.

In the drawing, 1 is the body of the gas range, having a gas cooking top 2 and oven 3 and a broiler oven d.

5 is a double burner, inclosed in a casing 6 and receiving air frein below through openings in plate 7 having bent up angles7 whereby the plate is strengthened and scidn cned and secured to the legs of the range. Over the gas burner and within the casing 6 is a. coil 10, having a cold water inlet 11, through which the water passes the coil 10 and out from the top thereof, is led to the bottom of a coil 12, to which it is connected and through which the water passes, to a preliminaryT tank 13 of the sides, sufficient I for small quantities of water used for kitchen purposes, thereby saving the heating of the water in the larger storage tank 14, used for washing and bathing. A valved pipe leads from said small tank 13 to a storage boiler 11i. The boiler la has a pipe l1', leading to coil l2, so as to form a circulation of the water in the boiler and in the coil, for reheating the water and again passed into the tanl la. rlhe boiler l is secured in the cross girt and further fully secured to a vertical plate 16, connecting plate 17 to the legs of body l. The for the burner under the coils 10 and 12 is received through pipes i7", which is secured to a casing 1S and is adapted to a needle valve 19, secured intact to a diaphragm 2O on casing 18. A diaphragm 1S is secured to casing 6 and connected by a pip-e 21, to the coil 10, so that when the pressure of water in the coil orcoils 10 and l2, or in the boiler 14 is above a pre-determined point, at which rthe temperature ofthe water isfdesired to be, the diaphragm 18 will automatically operate the needle valve 19J to out down the supply of gas to the burners 5. The outer tace of the diaphragm 18 is engaged by the lower end `ot a small lever which is fulcrumed on a projection on the casing 6. The upper en d of this small lever has an adjusting screw which bears against the casing 6 and is adapted to hold the lower end ofthe lever'in an adjusted position in which it will prevent the operation of the diaphragm 18 to Such an extent as to entirely out o the gas when its supply is automatically increased by the operation of the diaphragm 18f on the needle valve 19,

The outside part of the needle valve is provided with a stud 22 and may have a jaw nut, whereby the said needle valve may be adjusted, to be acted on by the diaphragm, actuated by the pressure of the steam on it, when the temperature and pressure is at the desired point.

At the end of the shelf 7 and below the 'boiler 1t, I may place and secure to said plate 7, a radiator 7 that may be connected up at its bottom through valved pipes, in the usual well known way, to a source of supply of hot water (such as the heater in the cellar or a source that may heat the kitchen) said radiator 7 on said plate 7, at its bottom, a pipe coil secured to the bottom side of the plate 7, which may lead to yradiators, in the several rooms of the house or apartment. A wire screen basket may be secured below plate 7 right under the burner, through which the air passes to the burner.

lia-ving thus described invention, l claire:

1 ".he combination ci a supporting trame, a water heating coil, a gas burner beneath said coil, means to supply gas to said burner, said means including an adjustable valve governing the supply oit gas to the burner, a diaphragm operated by the pressure within said coil and operatively connected to said valve, and adjustable means limiting the niov-ernent ci said diaphragm and prevent ing the closing ci said valve.

2. The combination ci a suppoming frame, a water heating coil, a gas burner beneath said coil, means to supply gas to said burner,

and limit the diaphragm and prevent the closing of said valve, and an adjustable set screw adapted to hold said lever in diierent positions of adjustment.

3. The combination of a supporting frame, a casing, a water heating coil within said casing and having a water inlet opening in the lower end thereof, a pipe communicating with and extending downwardly from the upper end of the coil, a second coil within said casing laterally adjacent to theV rst named coil and having its lower end communicating with the lower end of said pipe, a water tank communicating with the lower end of the first named coil and with the upper end of the second named coil, and gas burners beneath said coils.

4. The combination of a supporting frame, a casing, a water heating coil within said casing and having a water inlet opening in the lower end thereof, a pipe communicating with and extending from the upper end. of the coil, a second coil within said casing laterally adjacent to the first named coil and having its lower end communicating with thelower end of said pipe, a prelimi- SOREN C.
